Not sure what the default is on the install these days, but you also
might consider disabling reverse dns checking, in the
/var/qmail/supervise/smtp/run file.
my run file:
#!/bin/sh
QMAILDUID=`id -u vpopmail`
NOFILESGID=`id -g vpopmail`
MAXSMTPD=`cat /var/qmail/control/concurrencyincoming`
BLACKLIST=`cat /var/qmail/control/blacklists`
SMTPD="/var/qmail/bin/qmail-smtpd"
TCP_CDB="/etc/tcprules.d/tcp.smtp.cdb"
RBLSMTPD="/usr/bin/rblsmtpd"
HOSTNAME=`hostname`
VCHKPW="/home/vpopmail/bin/vchkpw"
exec /usr/bin/softlimit -m 12000000 \
/usr/bin/tcpserver -H -P -R -l $HOSTNAME -x $TCP_CDB -c "$MAXSMTPD" \
-u "$QMAILDUID" -g "$NOFILESGID" 0 smtp \
$RBLSMTPD $BLACKLIST $SMTPD $VCHKPW /bin/true 2>&1
it's the -H -P -R three lines from the bottom that disable it.

As been the problem for others the last days.
Check your blacklists , remove ordb.org entries (ordb.org does not
exists anymore).

Subject: [qmailtoaster] Why would it take 30 second to get the SMTP
greeting?
My system is taking a long time to give the SMTP greeting these days
- over 30 seconds in fact. There are generally less than 10
concurrent incoming jobs according to the logs - in fact there were
only 3 when I telnetted to port 25 last, but it still took 32 seconds
to get the greeting.
The only unnusual thing about this server is that I removed sa-learn
because of the amount of memory it was consuming. Could this be
affecting smtp?
The server is a dual-xeon 3.0Ghz with 2GB of RAM, so it should have
to horsepower to handle this.
